ATTACHMENT FOR HYDROCABBON-ENGINES.

Specification of Letters Patent.

Patented Sept. 2, 1919.

To all whom it may concern:

Be it known that we, WILLIA F. C. Srxxnnonen and LYNnnN F. Lxscnnnn,citizens of the United States, residing, respectively, at Carthage andSpringfield, in the with the gas to form a highly explosive mixture.

A still further object is to provide simple and efficient meansconvenient to the driver whereby the supply of moisture to the manifoldcan be minutely controlled, it being thus possible to maintain theengine at a desired efiiciency irrespective of the climatic conditions.It is a well known fact that when the atmosphere is heavily laden withmoisture, hydrocarbon engines attain greater elliciency than where theair is dry and rare, this being due to the fact that a larger percentageof moisture is admitted to the carbureter under one condition than underthe other. In order that the same desirable proportions of gas andn'loisture may be ob. tained irrespective of atn'lospheric conditions,the present invention has been devised.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combi-' nation andarrangement of parts and in the details of construction hereinafterdescribed andclaimed, it being understood that changes in the preciseembodiment of the invention herein 5 disclosed. can be made within thescope of what is claimed, without I de-partingfrogn'the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

Referring to the figures by charaetersof reference A designates theradiator of an automobile and Bthe manifold of the engine, the samebeing of any preferred type. The radiator has the usual overflow tube Oextending from the upper portion thereof and downwardly to a point closeto the bottom of the radiator.

The device constituting the present invention is designed as anattachment and can be applied readily by an ordinary mechanic at aslight cost. The attachment includes a tapered nozzle 1 shown in Fig. 5and which nozzle has a nipple 2. This nozzle is adapted to be screwedinto an opening 3 formed in the manifold B and is cou pled to a valvecasing 4 having a rotary valve 5 therein the stem 6 of which has a Atube 8 is extended from the valve casing and has a coupling 9 to whichis attached one end of a spring 10, the other end of the spring beingattached to the arm. 7 so that the valve is thus held normally in closedposition as shown in Fig. 2. The coupling 9 serves to connect thetube 8to a flexible tube 11 of metal or the like which can be readily bent toadapt the attachment to engines of different forms. This tube is coupledto a tubular men'iber 12 having a tapered tubular extension 13 at oneendadapted to be forced up into the lower end of the overflow pipe C. Avalve casing 14 is extended upwardl from the member 12 and has aremovale cap 15. Within this casing is arranged a ball valve 16 (seeFigs. 3 and 4) and which valve is normally mounted on a seat 17. Outflowapertures 18 are provided within the valve with the plate casing 14 butcommunication between these apertures and the interior of the tubularmember 12 is normally shut off by the valve 16. However, when the valveis raised, communication is established between the inte-' the member 12is held against downward movement relative to the overflow pipe C.

Attached to the dash D is a guide bracket 22 and extending from thisbracket and through the dash a flexible tubular guide 23 which can bemade of coiled wire and which, in the form illustrated, is extendedalong the steering post E and to an attaching plate 24 which straddlesthe steering post. This plate i held firmly on the steering post by aU-holt Secured to the plate 24 is a lever 26 carrying a springcontrolled dog 27 adapted to engage between radial ribs 28 carried bythe plate 24 and which cooperates with the dog to hold the lever 26against, movement. The ribs 28 are preferably formed ona flange 29formed Secured to lever 26 is one end of a controlling wire 30, thiswire bein slidably mounted within the tube 23 and bracket 22 and beingconnected to the arm 7. l 4 It is to be understood that instead ofmounting the lever 26 on the steering post E where it can be quicklyreached by the hand grasping the steering wheel, the said plate can beattached to the dash 31 as shown in Fig. 7.

Under ordinary conditions the valve 5 is closed and, therefore, anyvapor generated within the radiator will not be sucked into the engine-However, by means of lever .26 the wire 30 can be actuated to shift arm7 and move the valve 5 to open or partly open position. Thus vaporgenerated Within. the radiator will be sucked through the overflow pipe(J and the member 12 into the tube 11, thence through the nozzle 1 intothe manifold where it will mix with the mixture of and air and increasethe efliciency of the explosive mixture. In fact it has been found inpractice that where vapor is thus used, a smaller amount of gas can beemployed than where only a mixture of air and is used. Consequently aconsiderable saving of fuel is effected. By providing this means ofadjustment the engine will operate efficiently under all climaticconditions and a minute adjustmctit can always 0 water in the member 12.Therefore during the suction set up by the engine, this water will bedrawn into the manifold whereit will mix with the air and gas and thenbe directed into the explosion chambers.

What is claimed is: 1

1. An attachment for hydro carbon-engines including a valved flexibletube, a noz zle at one end for attachment to an engine manifold, atubular member at the other end having a tapered extension adapted to bewedged into the overflow pipe of a radiator,

said member having an outflow aperture in the top portion thereof, acheck valve for said aperture, and means adapted to be connected to theoverflow pipe for supporting the tapered extension in said pipe.

2. As a complete artlcle of manufacture an attachment for hydrocarbonengines comprising a flexible tube, a normally closed valvecarried thereby, flexible means for operating the valve, a nozzle at oneend of the tube'for attachment to the manifold of an engine, a tubularmember at the other end of the tube having an outflow aperture in thetip portion thereof, a check valve for said aperture, a taperedextension upon the member and adapted to be wedged-into the end of theoverflow pipe of a radiator, and means for attachment to said overflowpipe for supporting the extension in the pipe.

In testimony that. we claim the foregoing as our own, we have heretoaflixed our signatures in the presence of two witnesses.
